Leica M (Typ 240) and Ricoh GXR: Technical Data Comparison

Comparison of Technical Data | References

On this page, I compare the technical data of the Leica M (Typ 240) and of the Ricoh GXR with M-Mount expansion unit, which both are cameras for using M-mount lenses. The GXR is, however, an APS-C camera, whereas the Leica M is a full-frame format camera. Therefore, when M-mount lenses are used at the GXR, the focal length has to be multiplied by the crop factor of 1.5.

 

Comparison of Technical Data

Below I present selected technical data for the Leica M (Type 240) that I collected from various sources and compare them with technical data of the Ricoh GXR with M-mount expansion unit, which also uses M-mount lenses. I cannot guarantee that all the data is correct.

 Since the Ricoh GXR M-mount expansion unit has an APS-C sensor, the focal length has to be multiplied with the crop factor of 1.5.
Zoom --- Digital zoom: 4.0 x (3.6 x for movies)  
Filter diameter Depending on the lens used Depending on the lens used  
Sensor LEICA MAX 24 MP CMOS Sensor; 24 (23.7) Million pixels (effective); aspect ratio 3:2; no AA filter CMOS sensor (23.6 mm × 15.7 mm, approx. 12.9/12.3 million pixels (total/effective pixels), aspect ratio 3:2; no AA filter The Leica M (Typ 240) has about twice the numbers of pixels that the Ricoh GXR with M-mount expansion unit..
Max. Pixels 5976 x 3992 pixels (DNG; 24MP); 5952 x 3976 pixels (JPG; 24 MP) 4288 × 2848, 3456 × 2304 (3:2)  
Aperture range Depending on the lens used Depending on the lens used  
ISO Range ISO 200 – ISO 6400, Pull 100 available, Auto ISO; ISO values beyond 3200 are called "Push" ISO-Lo, ISO 200 – 3200, Auto, Auto-Hi  
Autofocus system None None  
Distance setting range Depends on lens used Depends on lens used  
Smallest object field Depends on lens used Depends on lens used  
Focus metering methods Rangefinder: double and split image
Live view: Focus Aid (screen magnification 5 x, 10 x) and Focus Peaking (three colors) 		Manual; MF assist (screen magnification, focus assist)  
Exposure modes Aperture priority, manual setting, TAv (Auto ISO in manual mode) Aperture priority AE, manual exposure  
Exposure metering Classic (strongly center-weighted), Live view: Spot, center-weighted, multi-field metering TTL metering in multi (256-segment), center-weighted, and spot metering (TTL metering with auto exposure lock)  
Exposure compensation -3 EV to +3 EV, 1/3 f-stops -4.0 EV to +4.0 EV in increments of 1/3 EV or 1/2 EV  
Automatic bracketing Exposure Bracketing: 3/5 frames, 0.5 / 1 / 2 / 3 f-stops -2.0 EV to +2.0 EV in increments of 1/3 EV or 1/2 EV  
Continuous picture
series		 3 fps, ≤12 pictures in series Noise Reduction on weak or off: 4 pictures
Noise Reduction on strong: 3 pictures
Noise Reduction on MAX: 3 pictures		  
Shooting modes Aperture priority / manual exposure / TAv (Auto ISO in manual exposure) Aperture priority / manual exposure /scene (movie, portrait, sports, landscape, nightscape, skew correction, miniaturize, high contrast B&W, soft focus, cross process, toy camera, electronic shutter) / My Settings  
Shutter speed range For aperture priority: (A) continuous from 60 s to 1/4000 s.
For manual adjustment: 8s to 1/4000 s in half steps, B: For long exposures up to maximum 60 s (in conjunction with self-timer T function, i.e. 1st release = shutter opens, 2nd release = shutter closes).)
1/180 s flash synchronization		 Photographs 1/3200 - 180 s, bulb, time (upper and lower limits vary according to shooting and flash mode)  
Self timer delay time/Interval timer 2 or 12 s; none Approx. 10 s or 2 s, or custom setting; intervals of 5 s to 1 hour in increments of 5 s More options for the self-timer for the GXR, no interval timer on the M (Typ 240)
       
LCD monitor 3" TFT LCD, approx. 920,000 pixels; scratch resistant cover glass (Corning®Gorilla®Glass) 3" TFT LCD, approx. 920,000 pixels (body)  
Electronic viewfinder (optional) Leica VF2 (or Olympus VF2), approx. 1.44 megapixels, tiltable 90 degrees Ricoh EVF2, approx. 920,000 pixels, tiltable 90 degrees The Leica viewfinder offers a larger image but shows pixels; I find it easier to use for manual focusing (without any focusing aids)
       
Video resolution/
frame rate		 1920 x 1080 pixels (1080p) or 1280 x 720 pixels (720p), 25/24 fps; 640 x 480 (VGA), 30 fps 1280×720 (720p), 640×480, 320×240
